Hi all,
   I've installed OTRS 2.4.7 on my Windows XP laptop.
I've configured my OTRS installation to authenticate users both on OTRS database and our internal company LDAP, setting configuration in Kernel/Config/Defaults.pm following instruction on administration manual (page 114 on pdf).
Always ok, I can login using local OTRS db account and using LDAP account.
After that I tried to recover a password for a OTRS db account using functionality exposed on customer login module. OTRS sens me correctly an e-mail with a link to activate change password, I receive the message in my mail box, check the url and OTRS fails with a web page containing the message:

Can't call method "GenerateRandomPassword" on an undefined value at C:/Programmi/OTRS/OTRS/bin/cgi-bin/../../Kernel/System/CustomerUser.pm line 466, <DATA> line 275.

Sadly in C:\Programmi\OTRS\OTRS\var\log\otrs.log there is no other information.

What's wrong with my multiple backend configuration?

Thanks for your response
